Abstract

Procedeu pentru separarea hidrocarburilor aromatice dintr-o sursa de alimentare, continând un amestec de izomeri aromatici ce include un paraizomer. Amestecul este adus în contact în conditii de adsorbtie cu un zeolit, supus, în prealabil, unui schimb de cationi ce îi imprima o selectivitate sporita fata de paraizomeri, însotita de adsorbtia selectiva a acestuia fata de adsorbant. în prealabil, zeolitul este tratat cu o hidrocarbura de alchilamina sau de alchilamine. Procedeul se aplica în special în industria alimentara.Process for the separation of aromatic hydrocarbons from a feed source, containing a mixture of aromatic isomers including a para-isomer. The mixture is brought into contact under adsorption conditions with a zeolite previously subjected to a cation exchange which imparts an increased selectivity to the para-isomers, together with its selective adsorption to the adsorbent. The zeolite is previously treated with an alkylamine or alkylamine hydrocarbon. The process is particularly applicable in the food industry.
